Harry Hess, Lawrence Morley and Drummond Matthews. Geologist Harry Hess was able to find more evidence on continental drift through his discovery of sea floor spreading. According to Investigation 4 it says “Geology professor Harry Hess, who had used sonar during World War II to map…

Ice Fishing Ice fishing began as a means of sustenance for people living in some of the coldest conditions on the planet. Over the years, ice fishing has become a very popular winter activity. Ice fishing can be done just about anywhere lakes and in some cases rivers freeze thoroughly enough to support the weight of a fisher and his equipment. In places like Canada and the Great Lakes region of the United States, locations in European countries like Germany and Russia, and Nordic nations like…

A dilemma to Florida’s coastline causing catastrophic issues to communities and habitats is coastal erosion. Coastal erosion is defined as a decrease in shoreline due to a physical event that could either be a short or long-term event. Examples of short-term events are waves and hurricanes; a long-term event could be in the rise in sea level (Pilkey, Cooper, 2004). In Florida, hurricanes are common due to warm waters in the Gulf of Mexico, thus creating massive amount of coastal erosion in…

World War II started a technological revolution for Canadian engineers and research. As Canada’s economy started to boom, Canadian development was one step ahead. Canadians insisted on changing their identity to an internationally noted world power. The Cold war ignited Canada’s change of identity. This was the first war where Canada was seriously threatened by attack coming to their territory. Canada changed its identity from being an agriculture and rural place to a strong nation with a…

are on the topic of consciousness and experience, Nagel is hinting at the comparison of how bats perceive the environment and how humans perceive the environment. Nagel states that “ We know that most bats perceive the external world primarily by sonar, or echolocation… of their our rapid, subtly modulated, high-frequency shriek.A bat is designed to connect the outgoing impulses with the subsequent echoes, and the information thus acquired enables the bats to make precise discriminations of…

[2] or by using other senses (i.e. sense of touch or hearing) [3]. Most of these systems require a module to capture the video and extract needed information with image processing (in some of these systems the information prepared by other ways like sonar [4-6], infrared [7], etc.). Depth is one of the important cues that people with the normal vision benefit it in mobility, navigation, picking up things, etc. Some of the visual prosthesis (e.g. audible visual prosthesis [5-6], tactile visual…

Flight MH370 is a mystery because we don’t know where the plane is now. Two vessels have covered 21,000 square miles in the Southern Indian Ocean and have not yet found any evidence of the plane whatsoever. They have been taking pictures with their sonar equipment but due to it being so far deep that the camera is not working correctly and…

The background of ultrasound imaging has led to improvements and made this imaging process more popular in the medical field. Ultrasounds started in the 1940s the idea was borrowed, “From sonar technology in World War II” (Allen 43). Ultrasound imaging has been around for over fifty years, and there are still new things to learn about the process of imaging. New discoveries are made frequently in the medical field, for example ultrasound used to only be two dimensional imaging, but now four…
